SnowConvert AI - Oracle Conversion Settings¶

Object Conversion¶

1. Transformer les synonymes : Indicateur signalant si les synonymes doivent être transformés ou non. Par défaut, ce paramètre est défini sur true.

2. Transformer les paquets en nouveaux schémas : Indicateur signalant si les paquets doivent être transformés ou non en nouveaux schémas.

   Veuillez vérifier l’appellation de la procédure d’activation et de désactivation de l’indicateur :

Input

CREATE OR REPLACE PACKAGE emp_mgmt AS
PROCEDURE remove_emp (employee_id NUMBER );
END emp_mgmt;

CREATE OR REPLACE PACKAGE BODY emp_mgmt AS 
PROCEDURE remove_emp (employee_id NUMBER) IS 
   BEGIN 
      DELETE FROM employees 
      WHERE employees.employee_id = remove_emp.employee_id; 
      tot_emps := tot_emps - 1; 
   END; 
END emp_mgmt; 

Output Default

CREATE SCHEMA IF NOT EXISTS emp_mgmt
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
;

CREATE OR REPLACE PROCEDURE emp_mgmt.remove_emp (employee_id NUMBER(38, 18))
RETURNS VARCHAR
LANGUAGE SQL
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
EXECUTE AS CALLER
AS
$$
   BEGIN
      DELETE FROM
         employees
         WHERE employees.employee_id = remove_emp.employee_id;
         tot_emps :=
                     !!!RESOLVE EWI!!! /*** SSC-EWI-OR0036 - TYPES RESOLUTION ISSUES, ARITHMETIC OPERATION '-' MAY NOT BEHAVE CORRECTLY BETWEEN unknown AND Number ***/!!!
                     tot_emps - 1;
   END;
$$;

Output with param disablePackagesAsSchemas

-- Additional Params: --disablePackagesAsSchemas
CREATE OR REPLACE PROCEDURE EMP_MGMT_REMOVE_EMP (employee_id NUMBER(38, 18))
RETURNS VARCHAR
LANGUAGE SQL
COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
EXECUTE AS CALLER
AS
$$
   BEGIN
      DELETE FROM
         employees
         WHERE employees.employee_id = remove_emp.employee_id;
         tot_emps :=
                     !!!RESOLVE EWI!!! /*** SSC-EWI-OR0036 - TYPES RESOLUTION ISSUES, ARITHMETIC OPERATION '-' MAY NOT BEHAVE CORRECTLY BETWEEN unknown AND Number ***/!!!
                     tot_emps - 1;
   END;
$$;

3. Transformer la date en horodatage :

Indicateur spécifiant si SYSDATE doit être transformé en CURRENT_DATE ou CURRENT_TIMESTAMP. Cela affectera également toutes les colonnes DATE qui seront transformées en TIMESTAMP.

Input

CREATE TABLE DATE_TABLE(
    DATE_COL DATE
);

SELECT SYSDATE FROM DUAL;

Output Default

CREATE OR REPLACE TABLE DATE_TABLE (
        DATE_COL TIMESTAMP /*** SSC-FDM-OR0042 - DATE TYPE COLUMN HAS A DIFFERENT BEHAVIOR IN SNOWFLAKE. ***/
    )
    COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
    ;

    SELECT
        CURRENT_TIMESTAMP()
    FROM DUAL;

Output with param disableDateAsTimestamp

-- Additional Params: --disableDateAsTimestamp
CREATE OR REPLACE TABLE DATE_TABLE (
        DATE_COL DATE /*** SSC-FDM-OR0042 - DATE TYPE COLUMN HAS A DIFFERENT BEHAVIOR IN SNOWFLAKE. ***/
    )
    COMMENT = '{"origin":"sf_sc","name":"snowconvert","version":{"major":1, "minor":0},"attributes":{"component":"oracle"}}'
    ;

    SELECT
        CURRENT_DATE()
    FROM DUAL;

4. Transformer les JOINS OUTER en syntaxe ANSI : Indicateur signalant si les jointures externes doivent être transformées en syntaxe ANSI uniquement.

5. Data Conversion Types: You can upload a JSON file below to define specific data types considering data type origin and column name.

General Result Tab¶

1. Comment objects with missing dependencies: This flag indicates whether the user wants to comment on nodes with missing dependencies.

2. Set encoding of the input files: Check General Conversion Settings for more details.

Description¶

Prepare my code: Flag to indicate whether the input code should be processed before parsing and transformation. This can be useful to improve the parsing process. By default, it’s set to FALSE.

Splits the input code top-level objects into multiple files. The containing folders would be organized as follows:

Copy

└───A new folder named ''[input_folder_name]_Processed''
    └───Top-level object type
        └───Schema name

Example¶

├───in
│       DDL_Packages.sql
│       DDL_Procedures.sql
│       DDL_Tables.sql

├───in_Processed
    ├───package
    │   └───MY_SCHEMA
    │           MY_FIRST_PACKAGE.sql
    │           ANOTHER_PACKAGE.sql
    │
    ├───procedure
    │   └───MY_SCHEMA
    │           A_PROCEDURE.sql
    │           ANOTHER_PROCEDURE.sql
    │           YET_ANOTHER_PROCEDURE.sql
    │
    └───table
        └───MY_SCHEMA
                MY_TABLE.sql
                ADDITIONAL_TABLE.sql
                THIRD_TABLE.sql

Requirements ¶

To identify top-level objects, a tag must be included in a comment before their declaration. Our Extraction scripts generate these tags.

The tag should follow the next format:

<sc-top_level_object_type>top_level_object_name</sc-top_level_object_type>

You can follow the next example:

/* <sc-table> MY_SCHEMA.MY_TABLE</sc-table> */
CREATE TABLE "MY_SCHEMA"."MY_TABLE" (
    "MY_COLUMN" VARCHAR2(128)
) ;
